CImage messed up color

I am using the CImage class to open a pair of jpg files ( Image.load() ) and show them on a dialog. My user then has the ability to draw a circle, rectangle, or just a line to "Mark Up" the images then save and/or print the new image. All that functionality is great BUT whenever I try to resize an image ( Image.StretchBlt()  or Image.draw()) the color gets messed up usually it gets very dark.  Just as a test I tried using the CPicture wrapper which encapsulates IPicture and while it DOES NOT mess with the color, some of the other functionallity is missing...  How can I get CImage to scale without changing the colors?

A little more detail: I get the client rectangle, determine how wide the images can be to fit nicely then create new rectangles using the new image width and the aspect ratio of the CImage image. Then I  draw or stretchblt using the new rectangle as the destination ( it lies inside the client dc ) and the CIamge as the source. mode is SRCCOPY. The displayed image is sized correctly and positioned correctly but the color is messed up dark...
